Introduction

Motivation

Australian Election Post - ABC

It is a contiguous cartogram as a whole, yet non-contiguous on the display.

Initial Map - AU 2022 Election

Hexmap

Non-contiguous display

Election details for each state

Goal -> To obtain a similar output

Research results (ongoing)

Relevant literature reviews

1. A Hexagon Tile Map Algorithm for Displaying Spatial Data

by Stephanie Kobakian, Dianne Cook, and Earl Duncan

Relevant R package: sugarbag (github)

Maps may illustrate and lead to misunderstanding or misleading statical information display.

Example: Normal Choropleth - AU Census data

Possible solutions: alternative cartograms based on the orignial geographical map

Output from the sugerbag package on AU Census data

2. Malaysia Election Data Visualization Using Hexagon Tile Grid Map (2018)

Relevant R packages & online News/Posts

R package - geogrid (github)

C++ -> core calculating algorithm for minimizing the total distance between the centroid of every original geography and its new centroid on the grid (Hungarian algorithm) + R

Example: UK - London boroughs

Example: US States

R package - tilemaps (github)

US data

Tilegrams - (2016)

US Election data, mainly JavaScript.

Fivethirtyeight Post github

2016 US Election data, mainly Python.
